Are the legs of a cat and fins of a whale homologous or anologous?
The legs of a cat and fins of a whale are analogous structures because they have different evolutionary origins but serve a similar function in terms of movement. Homologous structures would be when two species share a common ancestor and have similar structures with different functions.
Know whether or not gametes have homologous chromosomes?
Gametes are said to have homologous chromosomes, if they have same genes arranged in same order. During gamete formation meiosis precedes, therefore, individual gamete does not have its homologous counterpart. After fertilization, in diploid nucleus, homologous chromosomes are restored.
Do lamprey have paired appendages?
No, lampreys do not have paired appendages like fins or limbs. They have a single, continuous dorsal fin along their back that helps them maneuver in water.
What is homologous structure that is greatly reduced in size?
An example of a homologous structure that is greatly reduced in size is the pelvic bone in whales. These bones are remnants of hind limbs found in their land-dwelling ancestors, which have evolved to be much smaller and non-functional in whales due to their adaptation to an aquatic lifestyle.
What are statements that are true about chromosomes?
Selected Answer: The father donated one of each pair of homologous chromosomes, and the mother donated the other.

What are fish's limbs called?

Are Shark and dolphin fins analogous or homologous?
Analogous!
What are a fish's limbs?
The paired fins (pectoral and pelvic) are the nearest things fish have to limbs.
how many limbs does rhe box fish have?

Do dolphins and sharks have limbs?
no they have fins and tails but no legs or arms :)
What limbs do fish use for moving around?
fins and tail fin
Are the legs of a cat and the fins of a whale homologous or analogous?
Neither. Homologous structures are similar because two organisms came from a common ancestor. Analogous structures are similar because two unrelated organisms were subjected to similar environments. But the legs of a cat and the fins of a whale are not similar enough to be characterized as either homologous or analogous. The ancestors of whales were hoofed mammals, and one could argue that a hoofed mammal's leg and a cat's leg are homologous. However, after millions of years of being in the oceans, whales' fins have adapted such that they are now not at all similar to the legs of a cat.
How many fins does a Bull shark have?

Do fish have two pairs of limbs?
